sum 2 or 2 INVENTORS ROBERT ATALLARICO DON GOFF SUSPENDIBLE SLEEPING COCOON This invention relates to camping type sleeping equipment and more particularly to novel suspendible sleeping cocoons which are particularly suitable for outdoor camping and the like.

Sleeping bags are the most common type of portable bed presently in use for camping and the like. The usual practice with a sleeping bag is to place the bag on an air mattress on the round. In many situations it is not as desirable or as comfortable to sleep in this manner on the ground such as during the winter when there is snow on the ground. Further, for some applications such as back packing the additional weight and space taken up by an air mattress is prohibitive.

Accordingly, it is an object of this invention to provide a simple, durable and lightweight portable sleeping device which is suspendible from spaced points of support such as between trees, upright posts or the like.

Another object of this invention is to provide a novel and improved sleeping cocoon which facilitates the suspension of conventional insulated sleeping bags from spaced points of support during occupancy while utilizing the insulation properties of the bag most efficiently.

Yet another object of this invention is to provide a suspendible sleeping cocoon which is particularly lightweight and especially suitable for back packing and is principally characterized by having an insulated sleeping bag encompassing the body portion of the hammock on which the occupant rests in a suspended condition.

In accordance with the present invention, a sleeping bag and hammock are brought together with the body portion of the hammock forming an interlining for the sleeping bag so that the occupant rests directly on this body portion and the bag fully encompasses the occupant without compressing the insulation in the bag for a maximum insulation effect. A rectangular-type sleeping bag has the body portion of the hammock sewn to the bottom section of the bag or made an integral part of the bag with suspension lines being attached at spaced intervals to the ends of the body portion. In a mummytype sleeping bag the body portion is of a generally pod-like shape and has at least one suspension line secured to each end which in turn extends through openings in opposite ends of the bag without necessarily requiring a direct attachment of the body portion to the sleeping bag.

Other objects, advantages and capabilities of the present invention will become more apparent as the following description proceeds taken in conjunction with the accompanying drawings in which:

FIG. 12 is a sectional view taken across the sleeping cocoon shown in FIG. 8.

the end portion of Referring now to the drawings, the cocoon shown in FIGS. 1-7 broadly stated comprises an insulated sleeping bag 8 and a hammock 9 shown in FIG. 1 as being suspended from spaced upright supports 1 and 12. The sleeping bag 8 shown generally rectangular shaped bag having similar rectangular upper and lower sections 13 and 14 being foldable or hinged along one side 15 and provided with a zipper-type fastener 16 along the bottom 17 and the other side 18. This leaves an access opening 19 at the top for admitting an occupant into the bag. Upon releasing the zipper 16 the upper section I3 will then fold open to the same plane as the lower section or in a flat condition as shown in FIG. 3. The sleeping bag 8 may be of a conventional construction and as shown is composed of spaced inner and outer layers 21 and 22 of a fabric material such as Dacron or nylon which is stuffed with a suitable filler or insulation material 23 such as Dacron, down, feathers and the like.

The hammock 9 comprises an occupant supporting body portion 26 which made of one or more layers or a sheet material. This material is a strong and durable material and may be nylon, cotton, or the like. A plurality of bottom suspension lines 27 are suitably attached at spaced intervals along the foot end of the body portion 26 and converge at the other ends to a common support point at 28 which may be described as a ring or the like. A spreader member 3! in the form of a circular rod is disposed across and preferably sewn into the head end or top of the body portion to maintain this end in a generally flat condition during suspension. A plurality of top suspension lines 33 attach or are tied at one end at spaced intervals to the rod 31 and are arranged in two groups 330 and 33b and each group converges to common support points defined by rings 34 and 35 for tying at the ends of the suspension lines to the support post.

In the cocoon construction shown in FIGS. 1-7, the main body portion 26 is secured to or lines the inner or top surface of lower section 14 of the bag to in effect form an interlining in the bag on which the occupant rests, and the ends of the body portion project slightly beyond both the ends of the bag 8. The body portion of the hammock is preferably secured to the bag by stitching. This stitching may be arranged in a variety of patterns and as shown may be at spaced intervals across the top and bottom ends of the bag and along both sides as represented at 36. In this way the occupant is supported directly on the hammock and the insulation in the lower section 14 is not compressed during occupancy as it would be if the bag were disposed between the hammock and the occupant and accordingly this has been found to provide a better insulation effect for retaining body heat within the bag. While a separate layer of material is sewn to the bag to form the body portion to adapt existing sleeping bags, it is understood that the body portion may be an integral part of the bag serving as inner layer 21 or interlining for the lower section of the bag with the suspension lines directly attached to the ends thereof.

Referring now to the sleeping cocoon shown in FIGS. 8-12, this form broadly stated comprises a mummy-type insulated sleeping bag 38 and a generally pod-shaped hammock 39 shown in FIG. 8 as being suspended between upright supports 41 and 42. The mummy-type sleeping bag 38 is more of a generally tubular shape with a length of zipper 43 along the upper section of the bag adjacent the forward end to permit access of the occupant thereinto. The bag is composed of inner and outer cover layers 44 and 45 of a thin durable material such as nylon fabric material with a filler 46 between the layers forming the insulation for the bag being of a material such as Dacron, down or feathers. Stitching 47 is provided at spaced intervals laterally of the bag. The forward end portion 48 of the bag is enlarged and is in the nature of a hood with a head opening 50' and the bag tapers slightly inwardly toward the foot end and terminates in a somewhat upturned foot end portion 49.

The hammock 39 comprises a main body portion 50 which may be made from a rectangular shaped piece of sheet material folded in the middle along its length to provide opposed side sections 51 and 52 and define a top opening 53. The ends of the material are merged or bunched together and an upper line 54 is tied to the head end 55 of the body portion and a foot line 56 ties to the foot end 57 of the body portion. Suitable stiffeners may be folded into the bunched ends to give more body at the point here the line ties. In this way, the upper edges of the side sections 5! and 52 are supported in a spaced arrangement and when suspended are close together to form a narrow top opening. The occupant will then merely spread or separate the side sections to enlarge the top opening and climb thereinto. The sleeping bag is provided with a grommet 61 along the bottom at the head end and a grommet 62 along the bottom at the foot end to form reinforced holes in the bag. The grommets are readily installed by punching holes in the required places in the ends of conventional mummy-type sleeping bags. The suspension cords or ropes 54 and 56 extend through grommets 61 and 62, respectively, to attach to the exterior supports. The ropes or lines tying to the bunched ends of the hammock body portion in this way make it a generally teardrop shape as viewed from the top, it being wider at the intermediate portion and tapering or narrowing toward each end, as best shown in FIG. 10. The body portion of the hammock is therefore supported wholly within the sleeping bag but does not require it to be sewn into the sleeping bag. How ever, the hammock is maintained in position therein by the ropes extending through the ends of the bag. A further feature of this form of cocoon is that the hammock portion may be readily inserted into and removed from the bag for back packing, cleaning and the like. One material for the bag which has been found satisfactory for the body portion 50 is a lightweight nylon.

Although the present invention has been described with a certain degree of particularlity, it is understood that the present disclosure has been made by way of example and that changes in details of structure may be made without departing from the spirit thereof.
